Hi. I have a nissan patrol gu 2 2000 zd 30 auto and the
check engine light comes on when I am towing and working It a bit going up
hill above 3000 rpm I was wondering if any one has come accross this one. oh by the way It is running a 2006 motor that has done 68000ks but still with the 2000 electrics [melted a piston in the 2000 0ne].this problem also occurred with the old motor.I generally need to stop and turn of and restart to reset and then try to keep it under 3000 which some times is as good as useless especially in hilly country.appreciate any help.and is it anything to worry about.

Disconnect battery, leave overnight, reconnect battery
Just a thought !

Check the MAF.
Had the same problem only when it was cool and travelling along the great dividing range near the NSW QLD border. Never happened around
Brisbane.

Start with the simplest first, have you drained the fuel filter in case there is water in it, working the engine hard will increase the flow rate through the fuel filter and if the water float is close to the sensor it may be enough to push it up.
I have had this problem myself a few times, and now have one local servo I avoid buying diesel from.

Beegee It could be as simple as Snowy said, I wolud go just 1 step more and
check that fuel line hose connections are good, as sucking air into the line, after the fuel filter, will also cause the light to come on. These things can be done easily and at no cost, before you race off to the workshop for repairs that may not be nessisary. If in doubt about the spring type clamps fitted, replace them with worm drive hose clamps. This cured my issue with the engine light coming on, for over two years now.

I would suggest finding somebody who knows what they are doing and have the ECU fault codes extracted from the computer. This will tell you
where to start looking instead of taking guesses at anything and everything.

Hi Leroy
Many problems.
MAFF sensor is the most common.
Dirty fuel.
Open circuits in wiring earths
Pressure sesnsors
Dirty fuel
Retarded timing in fuel pump
Dirty fuel
Dirty fuel
EGR valve probs
And more dirty fuel
These things need impeccably clean fuel. Use genuine or reputable fuel filters and change them often. One gut full of dirty fuel I have seen stuff fuel pumps instantly. I have had success with genuine and Fleetguard filters. Sakura are also good as
well as the Japanese MAX brand. These are just the ones that work for me.

Thanks fellas, I drained fuel filter this morning,took it for a run warmed it up and booted it took it up over 4000 rpm and light didn,t come on. It did on old motor in same cicumstances. Haven,t tried towing yet though.Have heard EGR can cause some problems at high working revs with the warning light.

Hows it going Beegee,
If you get your hands on a workshop manual it tells you how to extract and read the fault codes that are logged in the ECU when the light stays on after draining the fuel filter . This lets you take any guess work out of fixing any problems you have.

Take the car to Nissan and get them to do diagnostic on it and take all the speculation and guess work out of the equation.
Is the engine still under warranty?
